Be it known that I, MAX RriNG, a citizen of the Republic of Germany,residing at172 Ismanningerstrasse, Munich, Germany, have inventedcertain new and useful Improvements kin Reenforced RailroadfCrossties,of which the following is a specification.

This invention has reference to means of increasing the duration ofrailroad cross-ties by providing the wooden cross-ties at the pointswhere the rails are supported with a lining plate of hard wood arrangedwith its fibers to run in the direction of the fibers of the cross-tiesor sleepers. It has been usual to employ such lining plates or blocks asa means of rendering cross-ties available `for use. which have becomeunfit for use by the widening of the spike holes, the surface `of thecross-tie being indented to a certain depth and `for a certain length,andthe indentation being thenfilled with one or more lining Aplates.orblocks.

However, the lining lmeans of the kind referred to and suggested by the-previous art have. not been very satisfactory and did not fully come upto the requirements of railroad opera-tion. 'The wooden lining latesheretofore" used were either arranged with their libres transverselywith relation to the tie, in which case the plates, though protectedfrom splitting, were loosened in the indentation as a result of changesof temperature, so that they required tightening; or, on the other handlining plates or blocks were used with their fibers in theolongitudinaldirection of the tie. With this arrangement there was the diiculty,however, that the plates were torn and broke open by the action of theweather and of the pressure of the rails. It has also been suggested tomake the indentation in the cross-tie of circular shape, in order toavoid tearing of the lining plate. Though with' this arrangement theinitial tearing and breaking open of the lining plate could be avoided,the pointed angular pieces on the surface of the. tie at the side of theindentation were forced away and broken off, and after the removal ofthese angles the lining plate itself had, of course, to give away andburst. These dificulties and inconveniences are overcome in thisinvention by providing strips of sheet metal with lateral ears, suchstrips being forced into the transverse joints between the edges of theindent-ations of the ties and the 8,' 1925. isenin No. 14,093.

edges of the lining plates or blocks disposed in the indentations withtheir fibers in the longitudinal. direction ofthe ties. The ears Yofthese strips are thereby forced both into the tie as well as into theliningplate with `the result that the lining plate is'l thereby Ysecured 1n a simple and unobjectionable mannerjbothv against bursting`and tearing, aswell as Vagainst displacement. j f

The inventlon will be more particularly Vdescribed with reference tothe., accompanying drawingA showing by way of e'Xemplific-altion apreferred form of embodiment of the principles of the invention, .Figure1 vbeiing a longitudinal section through the portion of the tie providedwithY the lining plate. Figure 2 is a top plan View according to Figure1,-and F igure 3 is a plan view ofthe l.metal strip employed forretainingthe lining plate in position and for securing the same againstbursting and tearing. l Figure lis a side view of the metal strip.Figure shows the original shape of the metal strip before the bending ofthe ears. In the cross-tie a the depression or indentation` b is out outin such -a manner that its fibers are running in the same direction withthose ofthe crosstie'. The lining plate c itself is provided with anindentation l in which the yfoot of the rail isfdisposed. In order toprevent bursting and tearing of this lining plate c y which the liningplate or block c is lodged in plate, each joint being'provided with ametal strip. These sheet iron strips are shown particularly in Figures 3to 5 of the drawing. The manufacture of these fastening and securingstrips is substantially effected as follows:

In the sheet metal strip f the cross cuts g and the longitudinal cuts hare provided, as appears from Figure 5 of the drawing. The sectionalportions 1, z', thereby obtained are bent alternatingly towards thefront and rear sides of the strip; and the ends of the stripf arelikewise bent respectively for- Ward and rearward, and by this means thestrip f is given the shape shown in Figures 3 and 4 of the drawing.

The block or lining plate o, shown in Figures 1 and 2 is provided at itsend faces, and

particularly at the vedges thereof, with incisions or notches at rightangle to the end faces and to the upper surface thereof andspaced fromeach other to correspond to the ears 0f the strips f. Then said strlps fare forced by hammer blows or the like into the transverse jointsbetween the tie and the lining plate c and in such a manner that theears 1,2 are made to engage respectively with the tie and the block orlining plate the ears 2 engaging with the incisions or saw-cuts in thelining plate, and the ears z', engaging with the transverse surface ofthe cross-tie itselfI adjacent the sheet metal strip The length of thestrips j' corresponds to the breadth of the cross-tie, so that the bentends of the strips are caused to bear upon the longitudinal faces of thetie and of the lining plate respectively.

By means of the ears the lining plate becomes subdivided intocomparatively small subdivisions or sections, so that upon the drying-upand contracting of the lining plate c this contraction cannot result inthe formation of broad or transverse fissures, aut will at most resultin the formation of small innocuous capillary fissures. There is ynofurther contraction of a lining plate mounted according to thisinvention in the longitudinal direction of the tie, so that the saidblock or lining plate c will always snugly and completely lill theindentation, while at the same time displacen'ient in the transversedirection is reliably prevented by the sheet metal strips f, ashereinbefore set forth.

While the invention has been described and shown -with reference to apreferred eX- emplification thereof it is to be understood that it isnot limited to this particular construction and arrangement of parts,but that it is susceptible of modifications and changes within the scopeand spirit of the invention, as definedthe appended 'claims'.

I claim l. A reenforced railroad cross-tie, including in combinationwith a topwise recess and a liningl plate in the recess of said tie withits fibers running substantially in the same direction as the fibers ofthe tie, and sheet metal strips disposedbetween the adjacent faces ofthe tie and of the lining plate, of lateral projections on said stripscngageable with the tie and the lining plate. 2. ln a reenforcedrailroad cross-tie having in combination, a topwise recess, a woodenlining plate in the recess of said tie with its fibers runningsubstantially in the direction of the fibers of the tie, sheet metalstrips between the adjoining faces of the tie and of the lining plate,and spacedly and angularly disposed lateral ears on said stripsengageable with the tie and with the lining plate and with the outersurface thereof.

ln a reenforced railroad cross-tie having in combination, a topwiserecess, a wooden lining block lodged in the recess of said tie with itsfibers running substantially in the direction of the fibers of the tie,sheetl metal strips transversely disposed between the adjoining faces ofthe tie and of the lining block, alternatingly oppositely directed,spacedly disposed lateral ears on said strips respectively engageablewith the tie and with the lining block, and oppositely dir ctcd ears atthe ends of said strips respectively engaging the outer surfaces of thetie and of the lining block.

In testimony whereof l affix my signature.V

MAX RPING.
